Ponchon-Savarit Diagram for Methanol-Water Mixture

Ponchon-Savarit diagram

pressure in mmHg

This Demonstration shows plots of the Ponchon–Savarit diagram (i.e.,

H

V

(y)

and

h

l

(x)

) for a methanol-water mixture at user-set values of the total pressure,

P

. In addition, the tie lines or isotherms are shown in green. The data obtained in our simulation, for

P=760mmHg

, agrees very well with those given in Henley and Seader's classic textbook [1], which are shown by red dots. The vapor-liquid equilibrium data is also plotted in a separate diagram.
